Memtest86+ (v5.00 beta 4)

So whats the recommended way to use memory test to see if your RAM is error free?

I just put the Cd in and let it boot form it and run, half an hour later, it brings up completed pass and no errors is that good enough or not?

10 full test 1 to 8 passes + looping test 5 around 50-100 times would usually be enough to tell

technically need 32 full passes at least due to way test 4 worked

Test 4 [Moving inv, 32 bit pat, cached]

This is a variation of the moving inversions algorithm that shifts the data pattern left one bit for each successive address. The starting bit position is shifted left for each pass. To use all possible data patterns 32 passes are required. This test is effective in detecting data sensitive errors in "wide" memory chips.

Thanks for the reply eva, I will now test my RAM correctly to see if its any good or not.

Thanks

Excellent forum, thanks for posting all this information! I prefer testing my RAM this way instead of using the Windows version of Memtest. I'm probably wrong but this bootable version of MemTest seems to do a better job at testing all locations of the RAM. In anycase thanks guys for posting all the information, links, and changelogs.

This app is great for finding any major errors and for testing if an OC is stable enough to at least boot into windows.

However I have found HCI memtest to be more stressful on the ram and NB that Memtest86+.
